HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 494,646, dated April 4, 1893.

Application filed February 16, 1892. Serial No. 421,698. (No model.) i

To all whom it may concern.-

Be it known that we, JAMES J. PARKER and WILLIAM M. MOFFIT, of Fulton,-in the county of Oswego, in the State of New York, have invented new and useful Improvements in Hose- Nozzles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Our invention relates to improvements in hose nozzles, and has for its object the production of a simple and effective device,which is practical and durable in use and economical in manufacture.

To this end it consists, essentially, in a frame having an outlet passage and an exit opening, a jaw arranged between said exit opening and movable into and out of said passage for varying the size or character of the stream thrown from the nozzle, a lever for engaging said jaw, a movable actuator for engaging the lever and operating the jaw, and in the detail construction and arrangement of the parts, all as hereinafter more particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, forming apart of this specification, in which, like letters indicate corresponding parts in all the views.

Figures 1 and 2 are respectively top plan and side elevation of ourinvention attached to a piece of piping or hose. Fig. 3 is a top plan view of the parts as shown at Figs. 1 and 2, the top plate being removed. Fig. 4 is an elevation similar to Fig. 2,with the exception that the front half of the outer casing and of the sleeve movable lengthwise on the casing is broken away for the purpose of illustrating the interior parts. Figs. 5 and 6 are horizontal, transverse, and longitudinal vertical sectional views taken respectively on the lines -5-5-, Fig. 4, and 6-, Fig. 3. Figs. 7 and 8 are top plan views of the inner jaws representing the same in their open position at Fig. 7, and as closed at Fig. 8. Figs. 9 and 10 are top plan views similarto Figs. 7 and 8 of the jaws arranged at the outside of the jaws shown at Figs. 7 and 8, and Figs. 11 and 12 are similar views of the jaws at the outside of the jaws shown at Figs. 9 and 10.

It is well known that it is particularly desirable to vary the size or character of a.

stream of water when using the same for extinguishing fires and similar purposes, as, for instance, if the flame is a considerable distance from the end of the nozzle the stream should be somewhat decreased in diameterif unable to reach the fire when of a larger diameter. Moreover when in close proximity to a large burning surface it is very desirable to throw a spray thereagainst instead of a stream of small diameter.

Our invention is designed to permit the fireman to quickly and practically change the size or character of the stream as the size or form of the surface burning or the distance therefrom may demand.

A represents the nozzle frame, which is provided preferably with a central passage a, an exit opening a, a head A', and a projecting flange A The outlet passage -a preferably tapers from its in-- ner toward its outer extremity, and discharg- -ing thereinto is the end of a pipe or hose -B, shown at Figs. 2, 4c, and 6 as screwing into the inner extremity of the frame A.

The exit opening a is preferably formed in a removable cap O suitably secured as by threads cand screws o to the outer face of the head A'.

-D represents the outer casing of our hose nozzle, which consists of a ring secured respectively at its upper and lower extremities to the flange -o of the cap -C- and the annular shoulder a of the flange -A E- represents a sleeve or actuator movable lengthwise on the frame -A- and formed with threads badapted to engage corresponding threads -a upon the peripheral edge of the flange A and providegd with the annular cams E'-- and -E'-.

--FGH- and --I represent the jaws for varying the size and character of the stream passed through the hoze nozzle, and,

as best seen at Fig. 6, these jaws are arranged one at the outside of the other between the exit opening a' and the inner end of the nozzle and at the outside of a similar opening a-- in the shell-A-. These jawsare IOO mounted in suitable guides f-gh and 7. consisting preferably of annular grooves of different diameters, the outer groove i being of the greatest and the inner one of the least diameter. There are preferably three corresponding jaws of each series as best seen at Figs. 1, 3, 5, and 7 to 12 inclusive. The three inner jaws F, when their adjacent edges are in close contact, form a passage on the outside of the passage -aof somewhat less diameter than said passage --a*', and consequently the diameter of the stream passed through the hose nozzle when said jaws are in operative position as shown at Fig. 8 is less than when the same are with drawn as shown at Fig. 7, and the opening a regulates the size of the stream. The jaws -G, when in their operative position, as shown at Fig. 10, still further reduce the size of the stream, and the next outer jaws E, which are formed with a series of perforations hcut up the reduced stream, and in connection with the exit opening which rounds outwardly at a throw the stream in a broad spray and cover a great surface. The cutting up of the stream is further effected as the water passes to the outside of the jaws E, as shown at Fig. 5. The extreme outer jaws I-, as best seen at Fi 1, serve to entirely shut off the passage through the nozzle.

It is evident that any desired actuator may be used for operating successively the aforesaid jaws -FGH- and I, but we prefer to use the form of actuator -E herein shown and described in connection with the movable levers J-J J and J as the same is extremely practical and is easily operated. These levers JJ' -J and J- are pivoted at J- to thefiangeA Their long arms are provided with slots j engaged with shoulders g h and i' upon rearwardly projecting arms F G l-I and I' on the respective jaws F G H- and -I, and the short arms of said levers are formed with the opposite bearing faces 7"- and f adapted to be engaged respectively with the cam faces -E'- and -E As will be readily perceived in the drawings the proportion of the short and long arms of the respective levers J-J J and J is so regulated as to give the respect ive jaws -F -Gr-H and I- the required differential movement, although said levers are actuated by the same cams.

It will be readily understood that, as the sleeve -E is screwed upwardly, the tapered face -eof the cam E'- forces the depending arm of the levers J- outwardly and rocks the upper extremity of its long arm inwardly, thus forcing the jaws F into the position shown at Fig. 8, and that, as the sleeve E- continues its upward movement, the levers J -J J and J are sucessively rocked in a similar manner and the jaws --G--I-I-- and I-- forced to their operative positions as shown respectively at Figs. 10, 12, and 1.

It will be noted that the outer face e'- of the cam -E is not of sufficient length as best seen at Fig. 4 to hold the lower ends of the short arms of the levers J J' J and J in their outward position simultaneously so that the inner jaws return to their inoperative position after their outward jaws have been subsequently brought to their movement of the corresponding jaws operated thereby we prefer to use a spring -K- having one end bearing against the inner face of said levers and the other secured at 7c to the shell a.

The jaws E are provided at their extremities with rearwardly extending lugs -L- adapted to bear against the adjacent faces of the respective guides in which said jaws move and the adjacent faces of the jaws G and I for supporting thejaws I-I in their operative position.

It will also be noted at Figs. 5and 6 that the rearwardly extending arms F'-Gll and -Iof the respective jaws -F-GH and I move through removable bushings M, which may be readily replaced when worn, and, as seen in Figs. 5, 7, 9, and 11, the respective jaws F-GH and I- are formed at their adjacent faces with corresponding lugs -n-, and receiving recesses -?t'- for correctly centering said jaws.

The operation of our invention will be readily perceived from the foregoing description and upon reference to the drawings, and it will be particularly noted that the parts are simple and strong, easily assembled, replaced or repaired, and the operation of the nozzle practical and effective. It is evident,.however, that the spring K may be dispensed with if desired, or replaced by a stronger spring for dispensing with the outer shoulder E and that other changes may be made in the detail construction and arrangement of the parts of our hose nozzle without departing from the spirit of our invention, hence we do not limit ourselves to the precise detail construction and arrangement of our hose nozzle.
